TLC2652Q-8D

Instrumentation, Op Amps, Buffer Amps Overview

The TLC2652Q-8D is a precision chopper-stabilized operational amplifier utilizing Advanced LinCMOS technology. It features an input offset voltage of 3.5 µV maximum at 25°C and 10 µV over the full temperature range. The device operates with supply voltages from ±1.9 V to ±8 V, providing rail-to-rail common-mode input capability that includes the negative rail. Key electrical characteristics include a minimum common-mode rejection ratio of 120 dB, a gain-bandwidth product of 1.9 MHz, and a typical supply current of 1.5 mA.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Chopper-stabilization circuitry continuously nulls input offset voltage across temperature, time, and supply variations.
• Rail-to-rail input and output design supports single-supply or split-supply configurations down to ±1.9 V.
• Internal clamp pin allows for reduced overload recovery time in high-speed applications.

Instrumentation, Op Amps, Buffer Amps Applications

• Strain gauge signal conditioning
• Thermocouple amplification
• Low-level transducer signal processing

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the Q-suffix designation confirms the -40°C to +125°C operating temperature range. Ensure the -8D package code corresponds to the 8-pin Small Outline Integrated Circuit (SOIC) form factor. Confirm RoHS compliance status matches project requirements. Validate that external compensation capacitors are included in the bill of materials as they are mandatory for operation.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when extremely low DC offset and drift are critical. The Q-suffix variant is required for environments exceeding standard industrial temperatures. Consider the TLC2654 if higher bandwidth or lower noise density is needed. Verify that the internal chopping frequency of 450 Hz does not interfere with the application signal spectrum.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the TLC2652 family of precision amplifiers. The Q-suffix specifically denotes automotive-grade reliability and extended temperature performance compared to the C or I suffix variants. It shares the same core architecture as the TLC2652A but with relaxed offset specifications suitable for broader industrial use cases.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

TLC2652M-8D offers military-grade temperature coverage (-55°C to 125°C). TLC2652AC-8D provides tighter offset voltage specifications (1 µV max) for commercial temperature ranges.
